Along with the Little Drummer Boy, this is a favorite Christmas song. I love the story of Simeon found in Luke 2:21-35. It is a trait of our Soveriegn God to establish confirmation of the TRUTH to His servants who are doing His will. Simeon stands as a witness bridging the Old Testament and the New Testament. Then there is Anna in verses 36-38 following Simeon in her testimony. God is good in establishing His word in Mary and Joseph's heart, and in establishing Truth for us who believe His testimony.
